Abstract

A frame section includes a flex circuit layer, a support layer, and a silicon substrate carrier. The flex circuit layer includes a plurality of communication lines and having a flex circuit window section. The support layer includes a support layer window smaller that the flex circuit window section so as to define an inwardly extending support shelf. The silicon substrate carrier is mounted on the support shelf in the support layer window and includes an optoelectronic device supported on the silicon substrate carrier. The optoelectronic device includes a set of photoactive components. The frame section is used for supporting the optoelectronic device within a fiber optic transceiver assembly which in turn is used for connecting to a fiber optic ferrule supporting a set of fiber optic communication fibers.
